# Quick grep for emojis from the terminal.
# You first have to download the UCD archive. It's only a few MB compressed.
# I use ripgrep for its speed but you can replace GREP by what you see fit.
# Bonus! Use this bash function to copy the first result in your X clipboard:
# mj() { emoji -u "$1" | xclip ; echo "$(xclip -o)" }
